as to facilitate operation, and one which further provides a new and exceedingly sturdy yet simple construction not adapted to be twisted out of place during use, and which also includes wholly new means for locating the hook relative to-the lower end of the upper bowl stem. Other objects of my invention are to provide a construe-- tionwhichis adapted to'be very cheaply manu-' factured and to be used in connection with standard strainers without appreciably increasing the cost thereof. These and other advantages oimy improved construction will, however, hereinafter more Iully appear.

In the accompanying drawinglhave shown for purposes of illustration one embodiment which my invention may assume in practice.

In this; drawing,- Figure 1 is a side elevation, partially in section,

my improvement Fig. 2 is an enlarged detail view of the lower end of the strainer, showing my invention applied thereto; Fig. 3 is a view similar to Fig. 2 but taken from the opposite side;

' Fig. 4 is an end view of the lower portion of I Fig. 8 as seen from the left, and

Fig. 5 is a detail sectional view on line 5-5 of Fig. 3. I

Inthis illustrative construction, I have shown the upper bowl l of a vacuum type cofiee maker having the usual stem 2 adapted to be inserted in and sealed in a lower bowl, not shown; this having a depending spring 4 disposed within the stem 2 and this spring herein also being connected at its lower end to the lower edge 5 of the stem 2 and to a usual pull member or chain 6 by an improved connecting I structure hereinafter deof an upper bowl and a strainer equipped with bowl I being provided with a usual strainer 8 Company, a corporation oi Cop- 1935, Serial a... 18.853

i'orm a generally usual U-shaped edge engaging portion 8. In my improved construction, how- 7 ever, it will be noted that, instead of providing a- U-shaped portion 8 or doubled wire substantially throughout its length, as shown in my prior Pat- 8 cut No. 1,967,983, I herein bend a portion 9 down- .ward and under the bottom of the U-shaped portion 8, and also provide anotherbend l0 upward,

and over the bottom of the U-shaped portion 8 substantially midway between the upstanding 10 sides oi the latter. Moreover, this portion i0 is extended vertically downward as at I l, substantially below the U-shaped portion 8 and substan-' tially parallel to the portion 4 but laterally oil-set with respect thereto. As shown, the portion ll 15 is also provided with a lateral extension 12 on its lower end extending 'over toward and disposed directly beneath the portion 1. In .the preferred construction, this pull i2 is also bent into the form of an eyelet i3 in alignment with'the por- 20 tion I and having a free end I4 bent into engagement with the bottom of the portion I2 and acting to enclose an intermediate portion IS on the chain 6 below the top ball IE on the latter.

Asa result of this construction, it will be noted 25 that the pull member or chain 6 acts directly in line with the portion] of the spring 4 so that op-'-' eration is markedly facilitated. Further, with the portions 9, III, II, and I2 provided herein, a construction is provided wherein the portion i2 is 80 strongly supported on the portion 8 in such manner as not to be pulled out of the desired relation with respect thereto and the member 1 Moreover, it will be noted that the portion ill provides very convenient locating means for the portion 8 85 relative to the edge 5 of the stem 2 as shown in Figure 1, locating the parts definitely in the desired position illustrated therein. Moreover, it will be observed that due to its location midway between the arms of the U-shaped portion 8, this 40 member ID will act to locate the member 8 deflnitely' on the end 01' the stem 2 should the edge 5 inadvertently come on the opposite side of the member l0. Further, of course, the pull on the member G'will remain in the desired alignment with the portion 1 irrespective of the relative location of 8 and 5. It will also be evident that the construction is exceedingly strong and sturdy and adapted to be manufactured at small expense. These and other advantages oi. the same will, however, be clearly apparent to those skilled in the art.

While I have in this application specifically described one form which my invention may as-' sume in practice, it will be understood that this form of the'same is shown for purposes of illustration and that the construction may be modified and embodied in other forms without departing from its spirit or the scope of the appended claims.

What I claim as new and desire to secure by Letters Patent is:

1. In a cofiee maker strainer, an upper bowl having a stem, a strainer in said bowl having a connection extending through said stem and including an elongated dependingmember having a hook connected to the lower end of the latter and engageable with the lower edge of said stem, and operating means for said hook rigidly connected thereto and disposed in substantial alignment with said depending member.

2. In a coffee maker strainer; an upper bowl having a stem, a strainer in said bowl having a connection extending through said stem and including an elongated depending member having a hook connected to the lower end of the latter and engageable with the lower edge of said stem,

and operating means or said hook comprising a laterally extending portion connected to and spaced below said hook, and a pull member connected with said laterally extending portion at a point in line with said elongated depending member.

3. In a coffee maker strainer, an upper bowl having a stem, a strainer in said bowl having a connection extending through said stem and having .9. hook connected to the lower end of the latter, and means in said hook for locating the latter relatively to the lower end of said stem.

4. In a coffee maker strainer, an upper bowl having a stem, a strainer in said bowl having a spring connection extending through said stem and having a hook connected to the lower end of the latter, and means in said hook for locating the latter relatively to said stem with the edge of said stem disposed in operative positions on either side of said locating means. I

5. In a coffee maker strainer, an upper bowl having a stem, a strainer in said bowl having a spring connection extending'through said stem and having a hook connected to the lower end of the latter, operating means on said hook, and locating means in said hook, said locating means comprising a portion dividing said hook into two stem edge receiving portions and said operating means being disposed in alignment with the portion of said connection carrying said hook.

6. A strainer connection for coffee maker strainers having a depending portion carrying a hook thereon, and a pull connection braced by the hook and disposed in substantial alignmen with said portion.

'7. A strainer connection for cofiee maker strainers having a depending portion carrying a hook thereon, and a pull connection overlying said hook.

8. A strainer connection for coflee maker strainers having a depending portion carrying a hook thereon, and a pull connection disposed in alignment with said portion and having a portion supported in said hook.

9. A strainer connection for coffee maker strainers having a portion carrying a hook thereon, and means dividing said hook into a plurality of stem edge engaging portions.

10. A strainer connection for coffee maker strainers having a portion carrying a hook thereon, and means dividing said hook into a plurality of stem edge engaging portions and having a 4 depending laterally extended pull member connecting portion disposed in alignment with said first mentioned portion.

11. A strainer connection for coflfee maker strainers having a portion carrying a book thereon, said portion and hook comprising a length of wire and having an end portion extended downward from the outer end of said hook and upward and across the inside of said hook and then downwardly again.

, 12. A strainer connection for cofiee maker strainers having a portion carrying a hook thereon, said portion and hookcomprising a length of wire and having an end portion extended downward from the outer end of said hook and upward and across the inside of said hook, said end portion carrying a laterally extending eye portion.

13. A strainer connection for coffee strainers having a hook and a pull connection comprising a part connected to the hook at the outer end of the latter and extending over and across the middle portion of the hook.
